The memory throughput of the new MacBook Pro: What it means and that's enough for you

Apple has introduced a duo of MacBook Pros, which differ not only in the diagonal of their display. Depending on your choice, you can also install them with various chips. We have a choice of two – M1 Pro and M1 Max. The first can be combined with up to 32GB of unified RAM, the second with up to 64GB of unified RAM. These differ mainly in throughput, where the first provides up to 200 GB / s, the second then 400 GB / s. But what does that mean?

In common professional notebooks, data must be copied here and there via Apple's slower interface. But the new MacBook Pro does it differently. Its CPU and GPU share a contiguous block of unified memory, which means that all parts of the chip access data and memory without having to copy anything. All this is done faster and with greater efficiency.

Comparison with the competition

Memory throughput (memory bandwidth) is the maximum rate at which data can be read or stored in semiconductor memory by a chip / processor. It is given in GB per second. If we look at Intel's solution, its Core X series processors have a throughput of 94 GB / s.

The clear winner in this comparison is Apple's "Unified Memory Architecture," which provides memory throughput at least twice as fast as Intel's direct competition currently supports. E.g. The Sony Playstation 5 has a throughput of 448 GB / s. However, keep in mind that maximum throughput also depends on many variables in the system and software workload, as well as the power state.

Geekbench tests show that the M1 Max with its 400 GB / s obtains about 10% better multi-core score than the M1 Pro with 200 GB / s. However, you must judge for yourself whether this value is worth a possible surcharge. Both machines are very powerful and depend on the style of your work. However, it is certain that a higher configuration has better potential with a view to the future, when it can still perform fast enough work over a longer period of time. Here, however, it depends on how often you change your workstation. Nowadays, 200 GB / s is really enough for most of the work you might want with a new MacBook Pro.
